I think the filter bags are an awesome idea.

I actually built a high water station (like the old elevated tanks to refill the steam trains) last year near my deepest pool. I can fill the water station and then gravity feed through a 2" hose to my trailer tank. The high station can then refill while I deliver that load of water.

I just suspend a 12v sump pump in the pool, so the water rate and velocity would be easily handled by a large filter bag! Easy peasy to just take the bag home and rinse it to get ready for the next irrigation day!

I usually only figure out that I have clogged emitters when I see one tree dropping its leaves. An ounce of prevention will definitely be worth a pound of cure!
